COP-WIN DER HEAD.

Application filed July 9, 1926. Serial No. 121,420.

This invention relates to cop Winder heads` and has for one of its objects to provide an anti-friction driving connection between the driving shaft and the reciprocable cop shaft or tube.

A furtherobj ect of the invention is to provide a device of the class described in which the said anti-friction connection is provided With an enclosed housing whereby it is protected against the entrance of dirt and the like.

A still further object of the invention is to provide a device of the class described Which Will be simple in construction, comparatively inexpensive to manufacture and more eficient in use than those which have been heretofore proposed.

With the above and other objects in view which will appear as the description proceeds, the invention consists in the novel details of construction and combinations and arrangements of parts more fully hereinafter described and particularly pointed out in the appended claims.

Referring to the accompanying drawing in Which like reference characters designate like parts in all the views:

Figure 1 is a longitudinal sectional elevational view of a cop Winder head embodying an anti-friction driving connection, constituting the present invention;

Fig. 2 is a transverse sectional vieW taken approximately on the plane indicated by the line 2 2 of Fig. 1;

Fig. 3 is an enlarged transverse sectional vieW taken approximately on the plane indicated by the line 3-3 of Fig. 1; and,

Fig. 4 is a fragmentary elevational view of the Winder head looking in the opposite direction from Fig. 1, and showing a cop partially formed.

Referring more especially to the said drawings the numeral 5 indicates a cop shaft Which is preferably square in cross section and which is adapted to be moved longitudinally relative to the hollow driving shaft 6 in the Well known manner, in order to form the cop 7. A Winder head 8 surrounds the said cop shaft 5 and is supported in position by means of a bracket 9 and rod or shaft 1.0, the said head being provided with the usual cones 11 for guiding and forming the cop.

The outer end of the cop shaft 5 is supported by means of a bracket 12 and the sliding rod or shaft 13 while its inner end projects into the hollow driving shaft 6, as is clearly illustrated in Fig. 1. The said driving shaft C is adapted to be rotated by any suitable Well known means not shown and it carries adjacent its end, a sleeve or collar 14 Wvhich is secured thereto as by the set` screw lo.

The said sleeve or lcollar 14 is p-rovidediadare provided at right angles to one another, v. r

as Will be clear from Fig. 3. The rollers 17 as Will be readily understood, bear against the four flat sides of the square cop shaft 5 and form a connection between the sleeve 14 and the said shaft 5 which, while serving to transmit rotary motion from the sleeve to the shaft, at the same time permit of longitudinal movement of the shaft, relative to the sleeve. The inner end ofthe shaft 5 is further provided With an anti-friction roller 20 which engages the inner surface of the hollow shaft 6, as Will be clear from Figs. 1 and 2. y

In order to protect the anti-friction drive rollers, and their journals from dust, dirt and the like, a housing 21 is provided, surrounding the said rollers, as clearly indicated in Figs. 1 and 2.

The operation of the device is generally the same as those now in common use, it being understood that the thread or twine 23 is fed from a spool or the like, under suit-- able tension devices and down between the cones 11 to the rotating cop shaft 5. This shaft is rot-ated through the anti-friction driving rollers 17 from the hollow driving shaft 6 as above described and as the top is formed the said shaft 5 is moved axially outwardly, as shown in Fig. 4, until the oop is completed When it is removed from the shaft, in order that a new one may be started in the usual Way.

It Will thus be seen that this invention pro vides an anti-friction means for transmitting rotary motion from the drive shaftto the cop shaft Whiie at the same time, permitting of longitudinal movement of the latter, relative to the former and that the said driving (rineans is housed or protected against dust and irt.

While one form of the invention has been illustrated `and described, it is ob-vious that those skilled in the art may vary the details of construction as well as the precise arrangements of parts without departing from the spirit of the invention, and therefore, it is not wished to be limited to thel above disclosure except as may be required by the claims.

What is claimed is:

l. In a cop winder mechanism, a hollow drive shaft; a rotatable cop shaft longitudinally movable. within said drive shaft; rollers carried by said drive shaft for transmitting rotary motion therefrom tosaid cop shaft, said rollers providing an anti-friction longitudinal slip connection between said shafts; and a rolle-r carried by the inner end of said cop shaft, engaging the innerl surface of said hollow drive shaft.

2. In a` cop Winder mechanism, a hollow drive shaft; a rotatable cop shaft, polygonal in cross section, longitudinally 1novable within said drive shaft; rollers carried by said drive shaft engaging the flat faces of said cop shaft for transmitting rotary motion from said drive shaft to said cop shaft, said rollers providing an antifriction longitudnial slip connection between said shafts; and a roller carried by the inner end of said cop shaft, engaging the inner surface of said hollow drive shaft.

3. ln a cop Winder mechanism, a hollow drive shaft; a rotatable cop shaft, polygonal in cross section, longitudinally movable within said drive shaft; rollers carried by said drive shaft engaging the flat faces of said cop shaft, for transmitting rotary motion from said drive shaft to said cop sha-ft, said rollers providing an antifriction longitudinal slip connection between said shafts; a dust excluding housing enclosing said rollers; and a roller carried by the inner end of said cop shaft, engaging the inner surface of said hollow drive shaft.

4L. ln a cop Winder mechanism, a hollow drive shaft; a rotatable square cop shaft longitudinally movable within said drive shaft; a sleeve rigid with said drive shaft; and a. plurality of rollers journaled in said sleeve at substantially right angles to one another, bearing against the flat faces of said cop shaft for tansmitting rotary motion from said drive shaft to said cop shaft, said rollers providing an ant-ifriction longitudinal slip connection between said shafts.

ln testimony whereof, I affix my si gnature.
